Or even the different scales of your own waste. Whenever I'm worrying about which bin to put my coffee stirrer in, I sometimes think about the shear volume of landfill that got hauled from our house when we did a major renovation. I'm sure 10 lifetimes of coffee stirrers wouldn't come close.

I think worrying about things like single-use shopping bags and compostable straws is great from a "keep pollution out of the environment" perspective, but I doubt they make a huge difference from a landfill usage perspective.
